我有一个 asp.net 页面,其中我使用枚举(属性在 app_code 的类文件中定义)
现在我的问题是每当页面得到回发时,属性中的枚举值就会重置为第一个
我什至尝试将属性设置为静态,但仍然没有帮助。
下边是我的枚举和财产声明:
private static UrlType _type;
public static UrlType UrlPattern
{
get
{
HttpContext.Current.Response.Write("GET: " +_type + "<br>");
return _type;
}
set
{
_type = value;
HttpContext.Current.Response.Write("SET : " +_type + "<br>");
}
}
public int VanityId { get; set; }
public enum UrlType
{
ArticleOnly,
ArticleCategoryCombination,
Normal,
TechForum
}
这就是我所说的:
public void BindRewrite()
{
GrdRewrite.DataSource = objVanity.GetAllRewriteVanities(Vanity.UrlPattern);
GrdRewrite.DataBind();
if (Vanity.UrlPattern == Vanity.UrlType.ArticleCategoryCombination)
{
GrdRewrite.Columns[2].Visible = false;
GrdRewrite.Columns[3].Visible = GrdRewrite.Columns[5].Visible = GrdRewrite.Columns[6].Visible = true;
}
else if (Vanity.UrlPattern == Vanity.UrlType.ArticleOnly)
{
GrdRewrite.Columns[5].Visible = true;
GrdRewrite.Columns[2].Visible = GrdRewrite.Columns[3].Visible = GrdRewrite.Columns[6].Visible = false;
}
else if (Vanity.UrlPattern == Vanity.UrlType.Normal)
{
GrdRewrite.Columns[2].Visible = true;
GrdRewrite.Columns[3].Visible = GrdRewrite.Columns[5].Visible = GrdRewrite.Columns[6].Visible = false;
}
}
protected void Page_Load(object sender, EventArgs e)
{
pnlAdmin.Visible = (objVanity.UserName == "host");
if (objVanity.UserName == "host")
Enable();
else
FieldsOpenForEditors(objVanity.SiteSupportUrlFormat);
if (!IsPostBack)
{
Vanity.GenerateListFromEnums(drpAdminUrlType);
if (objVanity.UserName == "host")
Vanity.UrlPattern = Vanity.UrlType.ArticleOnly;
else
Vanity.UrlPattern = objVanity.SiteSupportUrlFormat;
BindRewrite();
}
}
谁能告诉我如何在回发中保留枚举的价值
我认为 viewstate 可能是选项,但不知道如何存储枚举值和恢复枚举中的字符串值。
